There are several models that share the Gold Glove name. I'll describe them in order of price:
1. Gold Glove/Gold Glove Elite (model GG or GGE): these are entry-level gloves commonly available at your big box sports stores in the $129-149 price range. Shell leather is decent, laces are typical quality, but you will notice they are softer and less structured from the get-go. Binding and welting on current models are synthetic leather. Good thing is, they share the same tried-and-true patterns you'll find in better Rawlings gloves.
2. Vintage Gold Glove: these were from the '80s and '90s (correct me if I'm wrong). They share many of the same characteristics of the Horween USA made HOH gloves, but in a more reasonable price tag. You'd have to search eBay for these models, and IIRC, they only came in tan leather.
3. 50th Anniversary Gold Glove: an all-black model lineup with the gold thumb logo and wrist label. Quality wise, these were at the lower level, typical of what you'd find on a Gold Glove from a big box store today. People sell these mostly for the "value" of the gold labels, typically from $150-250 depending on condition. Pristine NWT versions with perfect labels would be most valuable.
4. Rawlings Gold Glove (model RGG): these have been around for a few years and are the most expensive model Rawlings currently offers, around $500 retail. Original RGG series were black, with varying amounts of gold accents. Newer models are mocha with gaudy (IMO) gold stampings and other gold accents. As mentioned above, these are very high quality and beautiful when new. Good collector's items.
